Understanding the Scenario:
* The organization needs to make 10 million features accessible in ArcGIS Online.
* The dataset must remain synchronized with the enterprise geodatabase to ensure it is up to date.
Replication Options Overview:
* Distributed Collaboration:Distributed collaboration enables sharing data across ArcGIS Enterprise and ArcGIS Online. However, it is not ideal for managing large datasets with frequent updates like this scenario.
* Geodatabase Replication:
* Designed for synchronizing data between enterprise geodatabases.
* Supports one-way, two-way, or checkout replication to ensure updates are consistently transferred.
* The best option for synchronizing a large dataset like this with ArcGIS Online via publishing workflows.
* Delete and Append:This approach would involve overwriting the dataset frequently, which is inefficient and unsuitable for a dataset with 10 million features requiring frequent updates.
Steps to Implement Geodatabase Replication:
* Useone-way geodatabase replicationto replicate the dataset from the enterprise geodatabase to a secondary geodatabase.
* Publish the replicated data to ArcGIS Online.
* Set up periodic synchronization to ensure the ArcGIS Online data reflects updates from the enterprise geodatabase.

Why the Correct Answer is B:Geodatabase replication is explicitly designed for synchronizing large datasets between geodatabases, ensuring data consistency and compatibility with ArcGIS Online.
